Boiler repair & service

Many older Waterloo, Cedar Falls and Waverly homes still heat with boilers. We keep them running safely and efficiently.

Boiler problems we fix

  • No heat or uneven heat from radiators or baseboards
  • Banging or knocking pipes
  • Leaks around the boiler, valves or radiators
  • Pilot or ignition problems
  • Pressure too high or too low
  • Circulator pump failures

Keep an older system healthy

Boilers can last decades with good care. An annual check keeps safety controls working and catches small leaks and worn parts early. When a boiler reaches the end of its life, we'll talk through replacement options, including high-efficiency boilers and ductless mini-splits for cooling.

Questions we hear a lot

Why are my radiators banging?

Often trapped air or water in steam pipes. It's usually fixable. Call for a check.

Do you service old boilers?

Yes. We work on older and newer hot-water and steam boilers.

β€œJohn came right away after I phoned him to let him know my central air stopped working. He knew exactly what the problem was and had it fixed and working within thirty minutes. Everything was explained to me and his price was very affordable.”

β€œHe was amazing. No upsale, he just quickly replaced a part he already had in his van. Professional and skilled are the words I would use to describe him.”
